Embodiments of techniques and systems for parallel XML parsing are described. An event-level XML parser may include a lightweight events partitioning stage, parallel events parsing stages, and a post-processing stage. The events partition may pick out event boundaries using single-instruction, multiple-data instructions to find occurrences of the '&#x3c;' character, marking event boundaries. Subsequent checking may be performed to help identify other event boundaries, as well as non-boundary instances of the '&#x3c;' character. During events parsing, unresolved items, such as namespace resolution or matching of start and end elements, may be recorded in structure metadata. This structure metadata may be used during the subsequent post-processing to perform a check of the XML data. If the XML data is well-formed, individual sub-event streams formed by the events parsing processes may be assembled into a flat result event stream structure. Other embodiments may be described and claimed.
